Why do you need to study about past presidents?
To forget your history is to be doomed to repeat it. We study
history to learn about the few things than our ancestors did right
in the world, and the MANY things that they did wrong, in the hope
that we will learn from their mistakes.
You see, we human beings can ONLY learn from mistakes. But
learning from OUR OWN mistakes is painful and dangerous. So we try
to learn from the mistakes that other people have made. And past
presidents have done a few things right, and gotten a LOT of things
wrong. We should learn from THOSE mistakes, so that we can go
forward from there and make new and innovative mistakes of our
OWN.
